HP LaserJet 1018 Printer - Manual (Page 106)

Using HP print cartridges
The following sections provide information about HP print cartridges and instructions for
redistributing toner and changing the print cartridge.
HP policy on non-HP print cartridges
Hewlett-Packard Company cannot recommend the use of non-HP print cartridges, either
new, refilled, or remanufactured. Since they are not HP products, Hewlett-Packard cannot
influence their design or control their quality. Service or repair that is required as a result of
using non-HP print cartridges will not be covered under the printer warranty.
NOTE The warranty does not apply to defects resulting from software, interfacing, or parts not
supplied by Hewlett-Packard.
Storing print cartridges
Do not remove the print cartridge from its package until you are ready to use it.
CAUTION To prevent damage to the print cartridge, minimize its exposure to direct light.
Some HP LaserJet print cartridge packages are stamped with an alphanumeric date code.
This code represents a 30-month period beyond the date of production that facilitates
efficient inventory management processes between HP and its resellers. It does not serve as
an indication of toner life (shelf-life) or relate in any way to warranty terms and conditions.
Print cartridge life expectancy
The life of the print cartridge depends on the amount of toner that your print jobs require.
The print cartridge for the HP LaserJet 1018 printer lasts for an average of 2,000 pages
(declared yield value in accordance with ISO/IEC 19752).
NOTE It is possible that the toner supply will outlast the mechanical parts in the print cartridge. If
the print quality begins to degrade under these circumstances, you must install a new print
cartridge, even if there is toner supply remaining in the cartridge.
This life expectancy assumes that you set the print density to 3 and turn EconoMode off.
(These are the default settings.)
Saving toner
While in EconoMode, the printer uses less toner on each page. Selecting this option will
extend the life of the print cartridge and reduce your cost per page, but it will reduce print
quality. HP does not recommend the full-time use of EconoMode.
